Concept Architecture
Concept
Theoretically, the Relative Value Scale (RVS) is a quantitative system that assigns relative numerical values to healthcare services according to the resources required to deliver them. These values reflect physician work, practice expense and professional liability costs, providing a standardised framework for determining reimbursement. The concept is grounded in resource-based costing, health services research and prospective payment theory and exists to ensure that provider payments are proportional to the relative resources consumed.
Mathematically, the Relative Value Scale represents each healthcare service by a relative value that serves as a weighting coefficient. The reimbursement associated with a service is obtained by combining its component Relative Value Units (RVUs) and multiplying the resulting value by an appropriate conversion factor. Geographic adjustment factors may also be incorporated to account for regional cost differences.
In practice, Relative Value Scales are used extensively in physician reimbursement systems, including the Medicare Resource-Based Relative Value Scale (RBRVS). Health economists employ the system to model healthcare expenditure, analyse provider incentives, estimate reimbursement levels and evaluate alternative payment mechanisms within health systems.
Purpose
Used to standardise healthcare service valuation, determine provider reimbursement, allocate healthcare resources and support economic evaluation of healthcare payment systems.
Mathematical Formulae
Primary Formula
Total Relative Value = Work RVU + Practice Expense RVU + Malpractice RVU
Supporting Formulae
Adjusted Relative Value = (Work RVU ? GPCIw) + (Practice Expense RVU ? GPCIpe) + (Malpractice RVU ? GPCImp)
Provider Payment = Total Relative Value ? Conversion Factor
Related Mathematical Methods
- Resource-Based Relative Value Scale (RBRVS)
- Relative Value Unit (RVU)
- Geographic adjustment
- Conversion factor
- Cost weighting
- Prospective payment modelling
Example
A procedure has:
- Work RVU = 2.10
- Practice Expense RVU = 1.35
- Malpractice RVU = 0.15
Total Relative Value
= 2.10 + 1.35 + 0.15
= 3.60
If the conversion factor is �39.00 per relative value unit:
Provider Payment
= 3.60 ? �39.00
= �140.40
The procedure therefore has a reimbursement value of �140.40 before any additional payment adjustments.

Frequently Asked Questions (6)
What is a relative value scale?
A system assigning a numerical value to each service reflecting its relative resource intensity, providing the structure for a standardised fee schedule.
Source: Hsiao et al. 1988
What does a relative value scale assign to each service?
A relative value scale is a system that assigns a numerical value to each service. The value it assigns reflects the service's resource intensity relative to others, so more demanding services carry higher values. It provides the structure for a standardised fee schedule, giving the relative weights that payment amounts are built on. The values in it reflect relative resource intensity, how much work and cost each service requires compared with the rest. It underlies a relative value unit, the unit in which those values are expressed. A ranking of services by resource intensity is what it assigns. Hsiao and colleagues (1988) set this out.

What does a relative value scale assign?
A relative value scale assigns a numerical value to each service reflecting its relative resource intensity, so it gives each service a value showing how resource-intensive it is relative to others, providing the structure for a standardised fee schedule. This assignment of values defines it. So a relative value scale is a system assigning a numerical value to each service reflecting its relative resource intensity, providing the structure for a standardised fee schedule.

What does a relative value scale provide?
A relative value scale provides the structure for a standardised fee schedule, so by assigning each service a numerical value reflecting its relative resource intensity, it gives the framework a fee schedule is built on. This provision of structure defines its purpose. So a relative value scale is a system assigning a numerical value to each service reflecting its relative resource intensity, providing the structure for a standardised fee schedule.

What do the values in a relative value scale reflect?
The values in a relative value scale reflect each service's relative resource intensity, so the numerical value assigned to a service shows how resource-intensive it is relative to others, providing the structure for a standardised fee schedule. This reflection of relative resource intensity defines it. So a relative value scale is a system assigning a numerical value to each service reflecting its relative resource intensity, providing the structure for a standardised fee schedule.
Source: Hsiao et al. 1988
How does a relative value scale relate to a relative value unit?
A relative value scale relates to a relative value unit as the system to its units: a relative value scale assigns a numerical value to each service reflecting its relative resource intensity, and a relative value unit is a unit quantifying the resources required for a service. So relative value units are the values within a relative value scale, connected as the system and the units it assigns to services.
